The common cause for the code P0430 to set in most cases is caused by a failing Bank 2 Catalytic Converter and in most cases replacing the converter will solve this code.

The code P0440 is an EVAP system leak detected code and the common cause for this one to set is a loose and or leaking gas cap. If your sure the cap is tight and not leaking then to determine where the leak is you are going to need to have a smoke test performed on your EVAP system. Start first with checking the gas cap and let me know what you find and we can work from there if need be.

I will tell you that...the things you have to go through to be an Expert are quite rigorous.
